Questions
How big is the Esp12e devboard PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp12e devboard use?
117 parts, built around the MP1470-MS, PL2303SA LF, MCP9700-E/TT and MAX1898EUB42-T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Esp12e devboard KiCad files?
From the EspIt/Hardware repository on GitHub, at the commit this page was made from: the board is esp12e_devboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp12e devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask EspIt before reusing the design.
